Summary0000265: Make mathsurround a glue
DescriptionIt is presently a kern. It would be very useful for short columns. OK, it requires reference counting, but just as any other glue.

I think it would also make mathsurround more usable if the possibility be added that it only get inserted if there is another glue following (or preceeding), via a primitive. This is to avoid inserting extra space when there is no space at all, such as before a punctuation mark. This would be easy to implement because the mathsurround does not actually enter the list while it is being formed, but just when it is packed.

Can you post an actual example where having an explicit glue and/or an extra inhibiting primitive would be useful?

Currently, I have doubts on the practical usability of this request.
